A showcase has a front wall which defines a showroom for a commodity in cooperation with other walls on a customer side, and includes a transparent portion. The showcase also has a support device that supports the transparent portion in such a way that the transparent portion is allowed to be translated to a direction away from the showroom.

A secondary restraint for restraining an animal in the event of the failure of a primary restraint. The secondary restraint preferably includes a length of nylon fabric having a ring on one end and a releasable hook on the other. The ring is sized so that the hook will fit through the ring. In use, the length of fabric is wrapped around the neck of the animal to be restrained, and the hook is passed through the ring. The hook is then attached to a ring on the primary restraint. If the primary restraint, such as a collar or harness, slips from the animal, the leash attached to the ring on the primary restraint will pull freely, tightening the secondary restraint and preventing the escape of the animal being restrained.

An apparatus for giving assistance in analyzing deficiency in a RTL-input program, includes a partial RTL creator which creates partial RTL description data containing logic description identical with logic description extracted from successive portions of input RTL description data, and having correspondence in signals identical with the same in the input RTL description data, an estimator which receives the partial RTL description data to execute a RTL-input program, and creates error-judgment data indicative of whether the RTL-input program contains deficiency, and an execution controller which controls a volume of logic description contained in partial RTL description data to be next created by the partial RTL creator, based on the error-judgment data, and outputs partial RTL description data causing the same deficiency as deficiency of the input RTL description data, and having a minimum volume of logic description.

The invention discloses a private transaction processing method, a public node, a transaction-related node, and a public blockchain system. The method includes initiating a transaction; generating a symmetric encryption key, and using the symmetric encryption key to pair the transaction content field of the transaction Encrypt the transaction content to obtain the first encrypted data; use the public keys of all transaction-related nodes that need to execute the transaction to encrypt the symmetric encryption key respectively to obtain the second encrypted data; pack the first encrypted data and the second encrypted data, and upload To the distributed storage system; receive the hash value returned by the distributed storage system; fill the hash value into the transaction content field; broadcast the transaction. The method provided by the invention can effectively guarantee the privacy data of users while retaining the security and reliability of a large number of nodes in the public blockchain system.

The smart suspension is compilation of air coils (air cylinder and air piston) as well as smart hydraulic shock absorber that in respect their roles are making comfort and improving vehicles balance. Regardless of the vehicle, the height adjustment system being used in smart suspension, adjusts the height and has the ability to drive in any desirable heights without losing a bit of comfort and safety (lowest to the highest elevations). There are two manual and automatic height adjustment systems, automatic system is being activated by disembarking passengers and manual system is set using the electronic key. These changes can range from 1 mm to 20 cm which in both conditions there would be no change in safety or any uncomfortable feeling.

The invention relates to a refitting device and method for quickly refitting an electronic lock into a wireless networking lock, and the electronic lock with the refitting device. The refitting device and method are mainly used for electronic locks. A power module is connected with a first plug-in module, a second plug-in module, a control module and a motor drive module. The positive electrode of a light-emitting diode of a first optocoupler is connected with the first plug-in module and the second plug-in module, and the negative electrode of the light-emitting diode of the first optocoupler is connected with one end of a third resistor. The other end of the third resistor is connected with the first plug-in module and the second plug-in module. The positive electrode of a light-emitting diode of a second optocoupler is connected with the negative electrode of the light-emitting diode of the first optocoupler, and the negative electrode of the light-emitting diode of the second optocoupler is connected with the positive electrode of the light-emitting diode of the first optocoupler. One end of a second resistor is connected with the collector electrode of a phototransistor of the first optocoupler, and the other end of the second resistor is connected with the control module. One end of a first resistor is connected with the collector electrode of a phototransistor of the second optocoupler, and the other end of the first resistor is connected with the control module.
